Steve hasn't been paying that much attention to the fireflies. He's been lucky so far, able to avoid the biting insects. But as he happens to pass by a familiar blond, he feels the sting on his shoulder, and soon after a firm smack. He turns to comment on that, but as he does a feeling of panic begins to creep over him. Steve's eyes widen, his hands shaking for no visible reason as he reaches up to steady himself using Thor's arm.

"What was that? It bit me." What if it was venomous? The thought seems ridiculous, but even so, Steve can't help but worry. What if he's slowing dying?
